What fluid are you pumping?

• Traditional motor oils (including synthetics): most piston and diaphragm pumps work.

• Multi-vis oils: use 3:1 or 5:1 piston pumps; higher ratios for high-volume or multiple dispense points.

• Gear oil: use a 5:1 pump (more viscous).

• Antifreeze: usually AODD (air-operated double-diaphragm) pumps in aluminum or poly; these are essentially 1:1 and give low outlet pressure — other options for long runs.

• Windshield wash (methanol): use poly or stainless pumps.

• Grease (NLGI 2): pump choice depends on distance, volume, and dispense points.

Site details we need

• Distance to the farthest dispense point?

• Number of dispense points? Will you use hose reels and what length?

• Types of vehicles serviced? (Passenger cars usually need ~1–1.5 GPM; trucks/large equipment may need 4–5 GPM or more.)

• Typical dispense volumes (e.g., car 4–8 quarts; large equipment much larger).

• Tank or drum sizes required?

• Need fluid management? If yes, how many fluids and how many total dispense points?

Notes

• Tubing size is set by required flow (GPM) and distance to the farthest point. If you’re not experienced with piping, consult an installer — we can help.
